Bug ID: 102638 Summary: Incorrect rendering in OpenGL 4 (Unigine Superposition + others) Product: Mesa Version: 17.1 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: mj.wilson.uk@gmail.com QA Contact: dri-devel@lists.freedesktop.org
Ryzen 1600X, 16GiB RAM, AMD RX570, Fedora 26 (clean install)
mesa-dri-drivers-17.1.7-1.fc26
Unigine Superposition Benchmark v1.0 (build 6184) Basic
Superposition and other OpenGL 4 (I guess) applications fail to render correctly. It seems that only one of the rendering stages is being shown -- it looks like the specular highlights from a cubemap or similar.
Tacoma (running on Unity) does the same.
Furthermore, there is a large disparity between the reported frame rate (30+) and the actual frame rate I see (perhaps 1/3 or 1/4 of that).
Both worked perfectly in Fedora 25 (same hardware) with mesa-dri-drivers-17.0.5-3.fc2.
I'm guessing this is a problem in the radeonsi driver.

--- Comment #4 from Timothy Arceri t_arceri@yahoo.com.au --- Unigine Superposition works fine for me. Do you still have this problem with more recent drivers? 17.1 has been unsupported for a while now.

--- Comment #5 from mj.wilson.uk@gmail.com --- Please consider this resolved. At some point as mesa packages were upgraded, this issue went away. I'm now on 17.3.6, and cannot reproduce the issue. Thanks.
